INSULATING-MACHINE Specification of Letters Patent.

Patented Sept. 10, 1907.

Applicationfiled August 13,1906. Serial No. 330,430.

To all 'wlio'm. it may concern: I

Be it known that I, HOWARD D. SAYLOR, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, 5

have invented certain new and useful Improvements in Insulating-Machines; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to insulating machines, and more particularly to stop mechanisms therefor, and has for its object to provide a thread-controlled mechanism for wire wrapping machines, arranged to stop the machine when the thread is broken.

Other objects and advantages will be apparent from the following description, and it is to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

In the drawings forming a portion of this specification and inwhich like numerals of reference indicate similar parts in the several views, Figure 1 is a top plan view of the present invention. Fig. 2 is a longitudinal section through the hollow shaft. Fig. 3 is a rear elevation, the rearward portion of the frame being broken away Fig. 4 is a side elevation. Fig. 5 is an en-- larged detail view, showing one of the thread cups in bottom plan. Fig. 6 is an enlarged detail view taken through one of the cups, theslide being shown in low ered position. Fig. 7 is an enlarged vertical section through one of the cups, showing the arrangement of the thread.

Referring now to the drawings, there is shown a frame 8 in which there are journaled vertically, a pairpf alining revolublesleeves 9 and 10 respectively, the former being the upper, while the latter is the lower sleeve.

' These sleeves are in spaced relation to each other; and

upon the upper end of each sleeve there is mounted a 16 which meshes with a similar gear 17 carried by the lower end of the sleeve 10, and splined upon the shaft 14, there is a movable clutch member 18 arranged for engagement with the clutch member 15 to rotate the latter with the shaft, at times. The movable member 18 has a peripheral groove 19 which receives a downwardly extending finger 20 carried by the outer end of a crank 22 located at the lower end of a vertical shaft 21 journaled in the frame, and this shaft is provided with a spring 23 arranged to hold it yieldably with the ,of its speed with respect to this shaft. is located at the bottom of the frame and receives 95 revolubly therewithin, a wire spool 41, a guide 42 being clutch members in mutual engagement. It will thus be seen that rotation of the shaft 21 will move the member 18 into and out of engagement with the member 15.

Arms 24 extend laterally from the shaft 21 and are,

curved to extend around the cups 11, the outer ends of these arms being turned away from the cups, as shown at 25. Vertical guides 26 are formed upon the outer surfaces of the cups 11, and these guides have stops' 27 at their lower ends. Vertically movable weighted these arms and the cups through rotation of the latter, when such members 28 are at the downward limits of their movements; When, however, the weighted members reach the lower ends of they gnides, rotation of the cups will cause the laterally projecting-ends of said members to contact with the inner faces of the arms 24 and push the same outwards, such movement of the arms causing the shaft 21, by which ,they are carried, to throw the clutch member 18 out of engage-.- ment with the clutch member 15, thus stopping the mechanism. To hold the shaft 21 against return movement under the action of the spring 23, a latch 30 is provided.

A counter shaft 31 isiournaled vertically inthe frame and carries a gear 32' meshing with a gear 33-on'the sleeve 10, this shaft 31 having a second gear 34-connected with a gear 35 carried by the sleeve 9, by means of an intermediate gear 36, so that the two sleeves are revolved in opposite directions. A drum wheel 37 is mounted upon the upper portion ofthe frame in the vertical plane of the sleeves, and has a friction disk 38 connected therewith which receives a friction pinion 39 adjustably mounted upon the shaft 31, the drum being thus driven by the shaft 31 and arranged for variation A bracket 40 provided to conduct Wire from the spool to the sleeve 10, through which and the sleeve 9 is passed, and is engaged around the drum 37,'from which it passes to a reel, as will be readily understood. A presser spring 42 is secured within each cup 11 to bear against the wire, as shown, and an eye 43 is formed upon the upper edge of each cup. v

In use, thread for insulating purposes is disposed in the cups 11, in the usual bolts, and the thread is passed through the eyes 43, then through the eyes 29, and finally through the eyelets 13 to the wire which extends between the fingers 12 and the springs 42, and the thread is wrapped around the wire to prevent slipping. The -weighted members 28 are supported in 11 raised position by the thread, as will be readily understood, so that the sleeves with their cups are free to dle A is carried by the shaft '21 for movement of the latter to stop the machine.

What is claimed is:

1. In a machine of the class described, the combination with a revoluhle thread-receiving cup, of a throw-out mechanism for the machine, a member carried by the cup for movement into and out of position to operate the throwout mechanism, said member being'arranged to lie yieldably in operative position and to receive thread from the cup to hold it normally in inoperative position.

2. The combination with a Winding machine including revoluhle thread cups, of'a throw-out mechanism for the machine including a movable operating shaft, arms carried by the shaft, and thread-controlled members mounted upon the cupsfor movement into and out of position to move the arms. I

3. In a machine of the class described, the combination with a revoluble thread cup, of a throw-out mechanism for the machine including a movable operating shaft, an arm carried by the shaft and extending in relation to the cup, a member mounted'upon the cup for movement into and out of position to engage the arm for-movement thereof, said member being arranged to receive thread from the cup and to be held thereby out of arm-engaging position.

4. In a machine of the class described, the combination with a 'revoluble thread cup, of a throw-out mechanism for the machine, an operating shaft for the throw-out mechanism, an arm carried by the shaft and extending in close relation to the cup. means for holding the arm at the limit of its movement in the direction of the cup and with the throw-out mechanism in position for operasleeves and the drive shaft, reverse gear and shaft connections between the sleeves, a thread receptacle carried by each sleey e, and an eye member connected with each sleeve for movement around a Wire passed therethrough and arranged'to' receive thread from the thread receptucles.

In testimony whereof, I afiix my signature, in presence of two Witnesses.
